Defence

What if we just arm every flying object in space now with a couple nukes, go to the moon and mars and but some defenses out there too ... and wait. Once the aliens come into our solar system we'll hijack them, take there ships and use it against them (maybe uploading a mac virus or something).

We would the "bad part of the neighbourhood" of the milkyway.

I wouldn't mind seeing more money flowing into the space industry, not just for robotics but getting humans up there (incl the moon and mars).

Anti-robot?

Anti-tank rocket => better tank armour

Bigger anti-tank rocket => even better tank armour

So

What will it take to kill a robot like that? A standard bullet to the robotic eye? Or another robot? Two other robots? Or perhaps a virus that a terrorist uploaded using his Macbook Pro (keeping up with the times)
